That probably is the lighest design possible, store and retrieve hashes only. But it can be expanded to return full contract state (getContractByID, for example) and probably even iterate over contract states. Fixes neo-project#2803.

Seems this is only for non-native contracts, uint is better.

I think it's GetContractHashes that is specifically for non-natives, but this one can return native contracts as well, it doesn't hurt. Otherwise we'll have to check for int overflows anyway.

Follow neo-project/neo#2807. Notice that this data is not cached, our previous implementation wasn't too and it shouldn't be a problem (not on the hot path).

This is an omission of neo-project#2807, even though native hashes are well-known GetContractById better be symmetric for all contracts. Related to nspcc-dev/neo-go#2837.

Fixes #2803. Not tested.
